#!/bin/bash

#TODO:
#~ Stats for .RAW files and naked DNG sequences, best as possible.
#~ --> Only read the file once into a long string, as opposed to once per setting.

#~ Better reading from Config File (update confEval).

#~ .darkframe generation.

#~ Better Preview:
#~ --> Essentially, a different module (like -e) for seeing, not developing, footage.
#~ --> To start, an option allowing one to see a single frame, developed. -DONE


#BUG: Relative OUTDIR makes baxpixel generation fail if ./mlv2badpixels.sh doesn't exist. Fixed on Linux only.
#MAYBE FIXED BUG: Run on all Charleston files; determine what's making Black Level not appear sometimes.

	  -->Image Defaults: Compressed 16-bit Linear EXR.
	  -->Acceptable Inputs: MLV, RAW, DNG Folder.
	  -->Option Input: From command line or config file.
	
$(echo -e "VERSION: ${VERSION}")
	
MANUAL DEPENDENCIES:

OPTIONS, OUTPUT:
	-i			IMAGE - Will output image sequence.
	
	-t [0:3]		IMG_FMT - Specified image output format.
	  --> 0: EXR (default), 1: TIFF, 2: PNG, 3: Cineon (DPX)."
	
	-m			MOVIE - Will output a Prores4444 file.
	
	-p [0:3]		PROXY - Create proxies alongside main output.
	  --> 0: No proxies (Default). 1: H.264 proxy. 2: JPG proxy sequence. 3: Both.
	  --> JPG proxy *won't* be developed w/o IMAGE. H.264 proxy *will* be developed no matter what, if specified.
	
	-s [0%:100%]		PROXY_SCALE - the size, in %, of the proxy output.
	  --> 50% is default.
	
	-k			KEEP_DNGS - Specify if you want to keep the DNG files.

CONFIG FILE:
	Next to each option is an uppercased item, ex. OUTDIR. In a convmlv config file, you can specify this option
	in the following format, line by line:
		<VARNAME> <VALUE>
	
	Some more notes regarding config files:
		-The global config file, read every time, will be looked for in $HOME/convmlv.conf.
		-Hashtags are considered comments, if and only if they are the first character in the line.
